A discrete random variable is a type of random variable that can take on a countable set of distinct values. Common examples include the number of children in a family, the outcome of rolling a die, ...

A discrete probability distribution function (also known as a probability mass function or PMF) describes the probability of each possible outcome in a discrete random variable. There are several ...

Statistical Distribution of Discrete and Continuous Random Variables: Core Concepts, Key Differences, and Applications in Scientific and Practical Research The statistical distribution of random ...

Continuous Variable: can take on any value between two specified values. Obtained by measuring. Covariance: a measure of the direction of the linear relationship between two variables. Discrete ...

Survey sampling is a statistical technique used to collect data from a subset of a larger population to draw conclusions about the entire population. By sampling, researchers can make inferences based ...

Generally it is a well-established notion that when the auxiliary variable is used appropriately in survey sampling, precision of the estimator is increased. Numbers of estimators exist in the ...
